Gross nitrification and mineralization rates^a

Sample	Gross nitrification rate (μg of N · g of soil−1 day−1)	Gross mineralization rate (μg of N · g of soil−1 day−1)
Soil from rice cultivar
KDML 105	0.25 A	1.24 A
Mahsuri	NSDb	1.28 A

Unplanted soil	NSD	0.93

^aMeans (n = 3) followed by the same letter are not significantly different based on least significant difference comparison of means (α = 0.05).

^bNSD, no significant dilution of the label was detected.
